While I could hardly recall my entire collection right now from school, I can mention a few I know I have, and put stars after ones I would highly recommend to someone who hasn't seen them:
4 of those $5.50 Beatles DVD's (I'll list titles later)
White Stripes: Under Blackpool Lights ***
Lord of the Rings Trilogy
OfficeSpace ***
Spaceballs
The Wizard of Oz
The Butterfly Effect
